The segregation improves reliability and overall safety of the switchgear assembly 10.
  • Typical compartments include a low voltage compartment, a circuit breaker compartment, a main bus compartment and cable compartment, for example.
  • the modular compartment 16 provides simplified removal and installation processes, thereby allowing replacement of the modular compartment 16 with a similar compartment or with a new compartment housing different electrical devices.
  • the modular compartment 16 includes a connection arrangement 20 that is configured to engage and form an electrical connection with the main busbar circuit portion 12. Typically, the electrical connection is facilitated by directly or indirectly coupling the modular compartment 16 to a branch busbar 22 disposed at a location proximate the connection arrangement 20 of the modular compartment 16.

  • the busbar aperture 28 and the portion 32 of the fastener 30 comprise a relatively square geometry, however, as noted above, numerous other geometries are suitable for imparting a non-rotational arrangement of the fastener 30 within the busbar aperture 28.
  • the fastener 30 includes a head portion 34 having a perimeter greater than the portion 32 of the fastener 30, such that insertion of the fastener 30 into the busbar aperture 28 leads to a fixed axial position, with respect to a direction of travel toward the modular compartment 16, of the fastener 30 upon engagement of the head portion 34 with a first side 35 of the branch busbar 22.

In the case of an insert, a copper material may be employed. Irrespective of the precise configuration, the recess 44 is shaped to rotationally retain a contact component 50 seated in the recess 44. To achieve rotational retention, the recess 44 and a base portion 52 of the contact component 50 are similarly shaped of a non-circular geometry. As is the case with the non-circular geometry of the busbar aperture 28, the portion 32 of the fastener 30 and the spout aperture 38, numerous non-circular shapes of the recess 44 and the base portion 52 of the contact component 50 may be suitable.
